Energy efficiency is one of the areas in which we've been investigating further cooperation with Ukrainian officials. Last fall we sent the head of our office of energy efficiency to Kiev. Actually in Odessa she met with a number of mayors of municipalities and cities in Ukraine, and they identified some possible opportunities for work on energy efficiency. We have a number of programs that just off the shelf we've been able to share with those decision-makers. One thing we did discover through those discussions was that the decision-making around energy use was often happening in a very centralized way, perhaps not surprisingly, so we're doing our best to reach out to those decision-makers.
We don't have any active program right now on energy efficiency, but it is one area in which we're looking at doing more.
